Environmental Chemistry Laboratory

Lab machine in a setting with other lab equipmentThe Environmental Chemistry Laboratory (ECL), a division of the Department of Toxic Substances Control, provides scientific leadership in analytical and environmental chemistry to protect public health and the environment from adverse effects of chemicals. 

ECL has primary responsibility within Biomonitoring California for developing analytical methods for persistent organic chemicals in blood, primarily serum

ECL scientists are internationally recognized leaders in the analytical and environmental chemistry of toxic substances.

To provide the scientific basis for regulatory actions, ECL scientists study regulated chemicals and chemicals of emerging concern in California.
